“Sounding very much like a candidate for president, today Vice President Joe Biden spoke at an AFL-CIO Labor Day event in Pittsburgh, Pa. “I’m mad, I’m angry,” Biden thundered, attacking the U.S. economy as “devastating for workers.”

Biden, who is openly considering running against Hillary Clinton in the Democratic primary, thanked “my friend” Richard Trumka, president of the AFL-CIO. ”

“There wouldn’t be a single basic right, from a 40-hour week to sick leave, there wouldn’t a single basic right out there … but for labor,” Biden said. “You build the middle class. That’s not an exaggeration.”
